GROUP ACTIONS 1. Introduction The symmetric groups S , alternating groups A
... coordinates in order is a function f : {1, 2, . . . , n} → R where f (i) = ci . Therefore the condition (g · f )(i) = f (g −1 i) amounts to saying g · (c1 , . . . , cn ) = (cg−1 (1) , . . . , cg−1 (n) ), which is precisely the action of Sn on Rn in the previous example. There are three basic ways we ...

A good reference for various proofs of that fact can be found in an article by Brennan and Machale [2]. Subgroups of prime index p, where p is the smallest prime divi ...

Direct Proof
... The simplest and most straightforward type of proof is a “direct” proof, which we’ll call any proof that follows straight from the definitions or from a direct calculation. Here’s a couple of examples: First we’ll prove the following statement: The sum of any two rational numbers is rational. This p ...
